Standard Form: Conversion of Numbers and Decimal Fractions

This lesson covers how to convert whole numbers, decimals, and decimal fractions into standard form (A × 10ⁿ, where 1 ≤ A < 10), as well as how to convert numbers already in standard form back into ordinary (full figure) form. You’ll learn the decimal-point movement rule for both large numbers (positive powers) and small numbers/fractions (negative powers). Essential for WAEC, NECO, and JAMB Mathematics.
